Explanation:

Correct sequence is Rapids- Ox-bow Lake-Estuary Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence.An ox-bow lake is a U- shaped body of water that forms when a wide meander from the main stem of   a river is cut off, creating a free-standing body of water.An estuary is a body of water formed where freshwater from rivers and streams flows into the ocean, mixing with the seawater.
